The Xfce project just announced the first maintenance release of the Xfce 4.4 branch, Xfce 4.4.1. There is a changelog, and you can download it from the Sourceforge download page. In case you lived under a rock the past few years: "Xfce is a lightweight desktop environment for unix-like operating systems. It aims to be fast and lightweight, while still being visually appealing and easy to use."
